Attached is the best written instructions I have seen on bending conduit. They are Irish and quite old but the basics are the same.
The best way of making offsets and bends I have found is to draw the required shape on the floor in chalk, then offer the conduit against the drawing to see where the bends should be.
On a different note it was once pointed out to me that there is a difference between the way Scots and English do conduit and having looked about it seems to be true. Scottish apprentices are taught to always use a lock ring with every thread cut, whenever you screw on a box or coupling there should always be a lock ring in there. And I have heard of guys being pulled up at their trade test for not using lock rings. In England lock rings are used much less frequently. Has anyone else noticed this? or knows why it came about?
